Angle Grinder Wheel/Discs

The most apparent disc and probably the most popular one among different types of angle grinder discs is the grinding disc. Grinding wheels come in different types and sizes (as the tasks they are expected to do and the size of the angle grinders are varied).

The hardness and smoothness of a grinding disc is measured by grit. Just like sandpapers, a lower grit number in a grinding disc means it is coarse and a higher number means the grinding wheel is less coarse. Low grit grinding discs remove the material faster, but they also produce more sparks and create a rougher look. They can also make slight burns and more scratches compared to high grit discs. Ronix produce high-quality grinding discs in various sizes.

Usages

Grinding wheels are mostly used for grinding, removing excess material of a surface, cleaning up cuts and prepare metal workpieces for welding. The are also used to grind out metal welds and sharpening various gardening tools like shovels.

Cut-off Discs

The second most used wheel for angle grinders is the cut-off disc. As the name clearly indicates, cut-off discs are used for cutting metal bars and metal sheets. Compared to grinding wheels, cut-off wheels are thinner in order to deliver the most accurate cuts. This is why working with them is more dangerous. If you suddenly change the position of angle grinders or use them in a position that makes them bend, they shatter easily. The flying small parts of a shattered cutting wheel are hazardous and can result in serious damages. Therefore, you should use high-quality safety gears when working with trying to cut with an angle grinder. Ronix cut-off discs are made from the highest quality materials which makes working with them safer compared to low-quality discs.

Usages

You can use cut-off discs for cutting metal bars, metal tubes and small pieces of metal sheets and plates. You can also cut out welds with them. For shortening the length of various bolts, it is also a good idea to use an angle grinder and a cut-off wheel.

Flap Discs

Flap Discs and grinding discs share a lot of similarities. The difference is that unlike grinding discs, flap discs are mostly used for finishing. This is why they have a smoother nature. Again, just like grinding discs, flap discs come in different grits. The higher the number, the smoother a disc is.

Usages

A flap disc is used to smooth a heavily grinded surface. It is also great at getting rid of burrs and scratches. Burrs and scratches are sharp and if one touches them without a protection (for example, a safety glove), the result is painful cuts. Additionally, you can chamfer and also take the sharp edges off with them and shine up gouged metal.

Wire Wheels

Wire wheels consist of a set of wires attached to a circle shaped base. Similar to other angle grinder discs, wire wheels are produced in different shapes and sizes because they are used for different purposes. If a wire wheel has thick, twisted bristles, it is considered more abrasive and is able to get the job done faster and easier. On the other hand, thinner and more straight bristles are considered less aggressive and are used for finer jobs.

Usages

If you want to remove rust from a workpiece, one of the fastest and easiest ways to achieve a clean surface is by using a wire wheel. These angle grinder attachments are also used to get the paint off of a surface.

Diamond Cutting Discs

Diamond cutting discs are undoubtedly the sharpest among angle grinder discs. These wheels have diamonds fixed on the surface of their edges. They normally have a cutting rim that the cutting process is done with them. The higher the cutting rim, the more durable they are and the longer you can use them. Ronix produces diamond cutting discs with a 10mm cutting rim which are efficient and extremely resistant.

Usages

Because of their diamond edges, the diamond cutting discs are suitable for cutting resistant and hard-to-penetrate materials like all types of granite. They are also used for both dry and wet cutting operations.

Polishing Pads

If you want a finished and shiny surface, then attaching polishing pads to your angle grinder can get you what you want. The name itself is self-explanatory; with a polishing pad, you can gently polish your desired surface. Just like any other attachment for angle grinders, polishing pads are produced in a wide range of shapes and materials that each, can create a unique finished look. Be sure to use polishing pads on an angle grinder that has a speed control switch. Because polishing requires a specific speed, not all angle grinders are suitable for polishing tasks.

Usages

For making the surface of a metal workpieces shiny, polishing pads are the right accessory for you! This is why polishing pads are widely used in auto body shops.
